Specification of Letters Patent. Patrgntggdl July 1?, 191

Application filed August 22, 1916. Serial No. 118,270.

in general with a view of rendering them more reliable in operation, andconvenient to control in such operatlon.

A further ob]ect of the lnvent1on is to provide a hydroplane which maybe safely driven at a high speed.

A further obJect of the invention is to provide improved and efficientmeans for.

forcing air through the openings in the sustaining or stabilizingplanes.

Other objects and advantages of the invention will be apparent duringthe course of the following description. 4

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a plan view of a hydroplane embodying my invention,

Fig. 2 is a side elevation of the same,

Fig. 3 is a central vertical longitudinal sectional view through thesame,

F ig. 4'. is a bottom plan view of one of the sustaining or stabilizingplanes,

Fig. 5 is a transverse sectional view taken on line 5 5 of Fig. 2, V

Fig. 6 is a plan view of gearing,

Fig. 7 is a vertical longitudinal sectional view through a suction fanor mechanism, and,

Fig. 8 is a transverse sectional view taken on line 88 of Fig. 7 withparts broken awa hi the drawings, wherein for the purpose ofillustration is shown a preferred embodiment of my invention, thenumeral 10 designates the hull or body portion of the hydroplane. Thishull has a forward bottom portion 11, which is approximately V-shaped incross-seeti0n,as shown in Fig. 5, and tapers downwardly. The forward endof this bottom portion inclines upwardly as clearly shown in Fig. 2, andthis forwardrend is tapered, as shown. The rear portion of the bottom ofthe hull is ofli-set upwardly, providing an elevated rear bottom portion12, which is curved in cross-section and has its concave surfacearranged outermost. As more clearly shown in Figs. 2 and 5, the bottomportion 11 has edge portions 13. which are transversely flat, andvertical vanes or blades 14 are rigidly secured to the edge portions 13and depend therefrom, as shown. The upper portion of the hull ispreferably closed by a top portion 14L, and this top portion has anopening 15.

Arranged upon opposite sides of the hull 10 and rigidly attached theretoare sustaining or stabilizing planes 16, which are identical. Each plane16 is provided centrally thereof with a longitudinally eXtending airchamber 17, the lower wall of which is provided with discharge aperturesor openings 18. As more clearly shown in Fig. 1, the apertures oropenings 18 are uniformly distributed upon the lower wall of the airchamber 17 and gradually increase in size toward the center of the lowerwall.

Suitably arranged within the hull is an internal combustion engine 19,preferably of the V-type, and preferably comprising two sets ofcylinders, each set comprising four cylinders. The engine has an exhaustpipe 19, which discharges into the passage beneath the bottom portion12, as shown. The engine 19 comprises a crank or driving shaft 20, whichextends parallel with the longitudinal axis of the hull and projectsoutwardly beyond the rear thereof.

Arranged upon the opposite sides of the shaft 20, within the hull 10,and near the rear end of the engine 19, are air suction fans or pumps21, which are identical. As more clearly shown in Figs. 7 and 8, eachsuction fan or pump comprises a shell 22, rigidly attached to the hull10 and this shell is provided with an air intake 23, as shown. Theoutlet side of shell 22 has connection with an air supply conduit 24,which is connected with the plane 16, and discharges into the airchamber 17. Disposed for rotation within the casing 18 is a tube 25,having apertures 26. This tube has the end thereof extending into theconduit 24 open while its opposite end is closed and rigidly connectedwith a driving shaft 27. Rigidly mounted upon therotatable tube 25 aresuction fans 28, comprising spaced disks 29, carrying therebetweencurved vanes 30. These propeller fans rotate in the direction of thearrow, as shown in Fig. 8, and the air passes inwardly between the vanes30 and discharges throughthe openings 26 into the tube 25. The airpasses froni' the tube 25 into the conduit 24 and then into thegirchamber 17. The air passes from the air 5 chamber vthrough the [op gsRotation is imparted to the shafts 27 by means of sprocket wheels 31,rigid 1y secured thereto, whi h er hg s e y pre he h ihe 132 ep eeh hais 2 extend inwardly to engage sprocket wheels 33, wh eh ar' rig hy mou tup e theeh f QQ- The propelling means forthe hydropiane eeihpriis ia hpre eil 3 h iig y s eh e it the ea en es t sha 2 and i te i pe ie 3 h eiie veh by s aft-36 h sh is jei rhel h u h e .h eh s e d e er l y in rexi y h fe wa e e th e ehkehet 2 e e hhe t d th r w t y imeah of 120suit ble geer h Atteeh "th a see f the he l he heht l y iheihg dihredleh -3 te heehhy e a 'h h ehehh e0 ehheeted y e r gin e whic th y hei eY by any it ble means ihe fihQWh) 1h he el ehetieh f t me he, he awhi h i i et it m t t n 2t he hat the air sh m-he 7 hd t th .atf e Pthrough th ape t i te 18- Th am h t e hi ppl a the h r .eha h item. theah l i" pumps e n ex e .ethet-dieeh reihs tihre h n t re eh .18.,whereby tehtia d e e nre e r e i hh l hi an main ain within t ai.ehaihhere 13- he xhehe air h e th iehs e pe ter h e p ni g l8 .eeihee'in ehtaet ith the a o th a iih f X er-ierl e th ham 1 nd when t hy h h ee e' hg at a h rate 0 peed he t eir x e i t thr h h th hperth e 1. e twith d g? .eute e a r, with th ie t there s h it i e h y to elevate theull out of the Water, whi j in win i h d n e im na i g hii ti n h tweenthe hull and the water.
